Astra Linux – Vulnerabilities in Linux, Linux-5.15, Linux-5.10

In the Linux kernel, the following vulnerability has been resolved: net/sched: clsapi: Remove blockcb from driverlist before freeing it. The error handler of tcfblockBind frees the entire bo-cblist when an error occurs. However, by that time, instances of flowblockCB are already in the driverlist...

CVE-2023-54193

CVE-2023-54193 affects the Linux kernel net/sched cls_api flow: when tcf_block_bind() errors, flow_block_cb objects were still in the driver_list, causing use-after-free. The fix removes flow_block_cb entries from driver_list before deallocation (the patch references show the changes). Affected: ...
